by taking lcm on first equation

9y-4x=2xy ------equation 3

by taking LCM on equation 2

15y-8x=7xy------equation 4

equation 3 is multiply with 2 then we get

18y-8x=4xy-----equation 5

subtract equation 5-equation 4

then we get

3y=-3xy

cancel 3y on both sides then we get x=-1

substitute x=-1 in equation 3 then we get

3y+4=-2y

y=-4/5,x=-1
